Decoherence of Bose-Einstein condensates in microtraps
Phys. Rev. A 69 (2004) 043602 (5 pages)


    We discuss the impact of thermally excited near fields on the coherent expansion of a condensate in a miniaturized electromagnetic trap. Monte Carlo simulations are compared with a kinetic two-component theory and indicate that atom interactions can slow down decoherence. This is explained by a simple theory in terms of the condensate dynamic structure factor.
